- file-name-1
-
Designates the file upon which the CLOSE statement is to operate. If
more than one file-name is specified, the files need not have the same
organization or access. File-name-1 must not be a sort or merge file.
- REEL/UNIT
-
Under OS/390 and VM, you can specify these phrases only for QSAM
multivolume or single volume files. The terms REEL and UNIT are
interchangeable.
Under AIX, OS/2, and Windows, REEL and UNIT are treated as comments. - WITH NO REWIND and FOR REMOVAL
-
Under OS/390 and VM, these phrases apply only to QSAM tape files. If
they are specified for storage devices to which they do not apply,
they are ignored.
Under AIX, OS/2, and Windows, WITH NO REWIND and FOR REMOVAL are treated as comments.
- The record area associated with the file-name is no longer available.
Unsuccessful execution of a CLOSE statement leaves availability of the
record data undefined.
- An OPEN statement for the file must be executed before any other
input/output statement.
- Under AIX, OS/2, and Windows any record locks and file locks held by
the file connector on the closed file are released.
If the file is in an open status and the execution of a CLOSE statement is unsuccessful, the EXCEPTION/ERROR procedure (if specified) for this file is executed.
